GEORGE PETTIT, JR, AND ALFRED BOWERS, OF BROOKLYN, NEW YORK.

COVERING FOR WALLS, CEILINGS, 84c.

SPECIFICATION forming part of Letters Patent No. 377,534, dated February "7, 1888.

' Application filed January 27, 1886. Serial No. 189,981. (No model.)

To aZZ whom it may concern;

Be it known that we, GEORGE PETTIT, Jr., and ALFRED BowERs, citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improved Covering for Walls and Ceilings, of which the following is a specification.

Our invention relates to an improved covering for walls and ceilings; and it consists, first, of a foundation of wood secured to the wall or ceiling, said foundation being provided with spaces at suitable distances apart to afford ventilation, and, second, of plates of metal provided with fluted or corrugated edges, the edges of said plates being concealed by a molding, the same being combined substantially as hereinafter described and claimed.

The objects of our invention are, first, to provide a covering for walls and ceilings, which can be cheaply constructed and which is adapted to the inside walls and ceilings of buildings and various kinds of passenger-conveyances, and, second, to afford means of ventilation. WVe accomplish these objects by the means illustrated in the accompanying drawings, in which v Figure 1 is a plan view of a metallic plate, A, surrounded by the molding B, a portion of the molding being removed to show the corrugated edges E of said plate. Fig. 2 is a side view showing the foundation D, molding B, and cap 0. Fig. 3 is an end view showingthe foundation D, with ventilating-spaces X between the boards which constitute the foundation-plate A, provided with semicircular curved edges. Fig. 4 is a side view showing the foundation D, provided with spaces X between the boards, plate A, provided with'corrugated edge E, molding B, and cap 0.

The foundation D, which consists of a sheathing of wood, is secured to the ceiling. Said foundation is provided with openings X at convenient points, which communicate between the ceiling and floor above. To this foundation the plates A are secured. The

edges of said plates are in aline with the openings in the sheathing, and are covered by molding B and cap 0, which are also secured to foundation D. If desired, the cap may be dispensed with and the therefor.

It will be observed that this device will atford perfect ventilation whenever it is used, as the air will'ascend and pass out between the moldings and plates and through the openings in foundation D into the space between thev ceiling and floorabove, and can be conducted outward by flues placed in the walls of the building, which contain slides for regulating the current of air.

We are aware that metallic plates have been used for covering ceilings, the edges of whichhas been covered by moldings and caps, as shown in Patent No. 58,881, January 19, 1875. We-do not claim such.

We are also aware that corrugated plates have been used for covering ceilings, the corrugations extending over the. entire surface and running in one direction only, as shown in Patent No. 330,915, November 24,1885. We do not claim such. But we are not aware that metallic plates provided with corrugated edges, the line of corrugation running at right angles with each edge, have ever been made before our invention thereof. I

What we claim, and desire to secure by Letters Patent, is

v.In a metallic ceiling, the combination of the following elements, to wit: the foundation D, consisting of a sheathing of wood provided with ventilating-spaces X at suitable distances apart, as shown, and a metallic plate, A, provided with fluted or corrugated edges, and molding B,-said molding covering and concealing said edges in the manner substantially as and for the purpose set forth.
